About StudyTexter Humanizer
StudyTexter’s AI humanizer, right inside Chrome, for any text. Select AI-generated text on a webpage, choose “Humanize” from the right-click menu and see in the sidebar how the AI detector GPTZero rates your original and the result. Emails, blog posts, ad copy, social posts, cover letters or essays: facts, figures and quotes stay intact.
How it works
1. Select the text and choose “Humanize” from the right-click menu. Or paste it straight into the sidebar, for example from Google Docs, Word or ChatGPT.
2. StudyTexter humanizes the AI text, and GPTZero checks both the original and the result.
3. Copy the result or open the same run in the full StudyTexter app.
What you get
• GPTZero score before and after: the original and the result sit in two tabs, each with its GPTZero score (Human + Mixed). Click a percentage to see the Human, Mixed and AI breakdown. The scores are classification probabilities, not proportions of individual passages.
• Every change visible: removed passages show up in red in the original, added passages in green in the result. You can hide the highlights.
• Your message stays: names, figures and references like (Becker & Lang, 2021, p. 14) stay in place. Only the wording changes.
• Many languages: the humanizer keeps the language of your text, whether English, German or one of more than 40 others. The sidebar is available in English, German, Spanish, French, Italian, Portuguese and Polish.
• Your document stays as it is: the extension never changes a webpage or your source document.
Account and word balance
Sign in with Apple, Google or email and password. The extension uses your StudyTexter account and the same word balance as the website. New accounts can try the humanizer for free with their available free words, after that StudyTexter’s packages apply. Your balance is split into free, subscription and purchased words. History and sidebar language are in the account menu.
Privacy
Your selected or pasted text is sent to StudyTexter and to the AI and checking providers named in the privacy policy so it can be humanized and checked. The original and the result are saved in your history. The extension does not read other pages, your browsing history or your clipboard.
